The Second American Professor of Chemistry at the ETH, William Dupré Treadwell (1885–1959)

Chemistry at the ETH was influenced by the contributions of two generations of Americans, Frederic Pearson Treadwell (1857–1918), the father, and William Dupré Treadwell (1885–1959), the son. Frederic Pearson Treadwell was the first American chemist to accept a permanent position at the Eidgenössische Technische Hochschule (ETH) in Zürich, Switzerland as an analytical chemist, while William Dupré Treadwell, the second American chemist at the ETH, broadened his interests to include physical and inorganic chemistry. Together their publication themes in analytical, inorganic, and physical chemistry endured for three quarters of a century, and their impact on the use of instrumentation at the ETH and in the chemistry world is still seen today.
